Didn't overlap the spreader...

We fertalized with some nitrogen to get rid of rust on a customers lawn-we didn't overlap with the spreader and now the lawn is looking like an american flag.

We're going to go back over it this weekend to get more fertalizer on the lines we missed, but my question is this-should we do the entire lawn over, of just the lines we missed? any recomendations and ideas are appriciated. Thanks

Good old fert and squirt. Always no matter what the directions say. When using your broadcast spreader throw from wheel track to wheel track. The advise on the bag is only good for the ingredients. Those people don't know how to spread it. Once you streak a yard you'll never do it again it's a learning process. Try and fill in the lighter green spots at a 2/3 rate. Or you could water the death out of it and mow it away in 2 weeks maybe. Be careful only hit the light spots. Another trick is always spread parallel to the road so everyone else doesn't't know you messed up. Especially on the high visibility ones. Spreading is like painting trim it out first until you get good then fill it in and in this case fill in the spots you missed.Good Luck
